Square Enix announced Final Fantasy YL, but unfortunately, it isn’t a video game. Yet, it’s still something you can “play” if you’re in Tokyo between November 15th and December 27th.

Final Fantasy YL is another of the initiatives launched to celebrate the 30th anniversary of the Final Fantasy series, in collaboration with JR East, the major railway company operating in Tokyo. It’s basically a stamp rally, but it does away with paper albums and messy traditional stamps. Basically, all you have to do is to locate posters in 29 JR East stations on the Yamanote Line and at the Suica Penguin Park in Shinjuku Station, scan their QR codes, and collect thirty different characters on your smartphone. If you catch them all, you get an exclusive wallpaper.
